§ PLUG-IN TRANSDUCER § 1 OUTPUT TYPE

SIGNAL TRANSDUCER

ANALOG PULSE TRANSDUCER
VFTP2 –■ UseInputs a DC signal of electric power or a current
transducer, and converts the signal into a pulse ofproportional frequency.

VFTP2 -915
(80×50×133mm/400g)■ Features
1. Either one of open collector output, voltage output and contact output isselectable as output signal method. In addition, in the case of AC auxiliary
supply and open collector output, product equipped with a power source forexternal relay's (DC24V, 40mA MAX) is manufacturable.
2. Function of cutting output against low input 1-10%.
3. Impulse withstands voltage 5kV, 1.2/50µs (between electric circuit and earth)positive/ negative polarity 3 times each is guaranteed.
